This is a follow-up to #12640. While profiling latency of working with a project with 8192 diagnostics I've noticed that while we're parsing the LSP messages into a generic message struct on a background thread, we can still block the main thread as the conversion between that generic message struct and the actual LSP message (for use by callback) is still happening on the main thread. This PR significantly constrains what a message callback can use, so that it can be executed on any thread; we also send off message conversion to the background thread. In practice new callback constraints were already satisfied by all call sites, so no code outside of the lsp crate had to be adjusted. This has improved throughput of my 8192-benchmark from 40s to send out all diagnostics after saving to ~20s. Now main thread is spending most of the time updating our diagnostics sets, which can probably be improved too. Closes #ISSUE Release Notes: - Improved app responsiveness with huge # of diagnostics. |

Licensing
License information for third party dependencies must be correctly provided for CI to pass.
We use cargo-about to automatically comply with open source licenses. If CI is failing, check the following:
- Is it showing a
no license specifiederror for a crate you've created? If so, addpublish = falseunder[package]in your crate's Cargo.toml. - Is the error
failed to satisfy license requirementsfor a dependency? If so, first determine what license the project has and whether this system is sufficient to comply with this license's requirements. If you're unsure, ask a lawyer. Once you've verified that this system is acceptable add the license's SPDX identifier to theacceptedarray inscript/licenses/zed-licenses.toml. - Is
cargo-aboutunable to find the license for a dependency? If so, add a clarification field at the end ofscript/licenses/zed-licenses.toml, as specified in the cargo-about book.
